BABY-JUMPER.

Serial No. 462,998.

T0 all whom it may concern:

Be it known that I, GEORGE T. GILsoN, a citizen of the United States,and a resident of Lewiston, in the county of Nez Perce and State ofIdaho, have invented a new and Improved Baby-Jumper, of which thefollowing is a full, clear, and exact description.

This invention relates to a class of springsupported seats for infants,that are hung from an overhead support ant. are technically termed babyjumpers, and the purpose of the invention is to provide novel details ofconstruction for a device of the character indicated, which are simple,durable and convenient, and that afford a safe, comfortable seat for asmall child, whose natural motions will cause an elastic jumping movement of the seat and its occupant.

The invention consists in the novel const-ructio-n and combination ofparts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a perspective View of the improved baby jumper having afront portion thereof adjusted for permitting the seating of a childthereon; Fig. 2 is a partly sectional enlarged side view of the device;and

Fig. 3 is a plan view of the same, showing parts in closed adjustment byfull lines and opened by dotted lines.

The body of the seat of the device, consists of two flat side pieces 5,5, formed of wood, and preferably having parallel side edges, thesesimilar members being connected at their lower ends by a transverse seatboard 6, of suitable dimensions for effective service. At an equalproper distance above the seat board 6, the side pieces 5 are reduced inwidth forming two hanger arms 5 thereon, and producing two shoulders a,a, of an equal depth at opposite points where the arms join the sidepieces. A curved back piece 7, is affixed at its ends upon the arms 5where they join the side pieces 5, and said back piece is furthersupported by a curved brace 8, that is secured at its ends respectivelyupon the seat board 6 and back piece 7, at their centers. The brace 8 iscurved forwardly and upwardly from the seat board 6, providing an arm orhorn 8 which has less height than that of the brace 8.

; The portions of the brace 8 and arm 8* that are seated and secured onthe seat board 6, are similarly rounded or rendered convex in crosssection, as at 6, thus removing their corners, and the front and rearcorners of the seat board 011 its upper side are similarly removed so asto avoid discomfort to the occupant of the seat. A curved guard bar 9similar to the back piece 7, is provided for the forward support of achild seated in the improved chair or seat, and

p to adapt it for such a purpose one end of said guard bar is hingedupon a correspond ing frame piece 5, at a shoulder a thereon and is thusadapted for adjustment toward and from the opposite frame bar 5. Uponthe free end of the guard bar 9, a ring eye (5 is secured, which willreceive the nose of a hook (Z pivoted upon a respective hanger arm 5when the guard bar is rocked toward said arm, and is seated thereon nearone of the shoulders 64.

To adapt the device so far as described for its service as a babyjumper, a preferably spiral coiled spring 10 is secured by one end onthe upper end of each hanger arm 5. At their opposite ends the springs10 are cured upon the ends of a yoke bar 11, from the center of which asuspension rope 12 extends to a point of overhead support, which may bethe ceiling of a veranda, or room, and have such a length including thatof the springs 10, as to dispose the seat board (3 a proper distanceabove the floor, so that when a child is seated on the seat board andsecured from release by its own efforts, the feet of the infant willslightly touch the floor. The natural activity of the occupant of thechair or seat will cause an expansion or contraction of the springs 10,and thus give a jumping motion to the seat and the baby it supports. Ofcourse, it will be understood, that a soft cushion or the like may beplaced on the seat board (3, and thus conduc'e to the infants comfort.

It will be noted that the relative position of the hook and eye (Z, (Z,will prevent them from being released the baby. Further more, theskeleton form given to the seat and attachments thereto affords freeventilation, that is essential for the health of a growing infant. Thegreat convenience afforded for iii the seating of a child in the chair,and for its removal as may be desired, are advantageous features of theimprovement.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A baby jumper, comprising a pair of hanger arms, a seat board securedto and connecting the lower ends of the hanger arms, a curved backhaving its ends secured to the hanger arms a suitable distance above theseat, a curved guard bar hinged to one of the hanger bars and having adetachable connection with the other hanger bar, a curved and rearwardlyextending brace secured to the seat and back, and a curved hornextending forwardly from the seat.

The combination with resilient suspending means, of a pair of hangerarms, a seat board that spaces the hanger arms apart parallel with eachother, a curved brace extended rearward from the seat board at itstransverse center, a curved back support mounted upon the brace andsecured at its ends on the hanger arms, a horn projecting forwardly fromthe seat and a hinged curved guard bar at the front of the seat board.

The combination with resilient suspending means, a pair of hanger armspendent from said means, side pieces at the lower ends of the hangerbars, and a trans verse seat board joined at its ends to the lower endsof the side pieces, of a curved brace extended rearward and upward fromthe seat board, a curved back support secured at its center on the upperend of the a curved guard bar hinged at one end on one of the sidepieces, and means carried by one end of the guard bar, adapted fordetachably securing said end upon a respective hanger arm.

a. The combination with a suspended rope or the like, a yoke bar on thelower end of said rope, springs pendent from the ends of the yoke bar,hanger arms pendent from the springs, side pieces on the lower ends ofthe hanger arms, and a seat board secured by its ends transversely onthe lower ends of the side pieces, of a brace piece curved rearard andupward from the center of the eat board, a curved back support fixed atits center on the upper end of said brace piece and at its ends on theside pieces, a horn curved forward and upward from the seat board, acurved guard bar hinged at one end on one of the side pieces, a ring eyeon the free end of the hinged guard bar, and a hook on the hanger. arm,that will engage the ring eye when the end of the guard bar is seatedupon the side piece near a respective hanger arm.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
